Troubleshooting Tips
Diagnosing problems. | Print quality and service configuration plots: You can use |
| these plots to help diagnose problems. (See ' pages 8;46 and 8;51). |
|
|
Firmware;code | Print a setup sheet or a service configuration plot to check the |
revision level. | firmware;code revision level that the plotter is using. The plotter |
| may be using in;built firmware, or firmware from a flash ROM |
| SIMM. (Which firmware? ' page 8;3). |
|
|
Repair and calibrate. | After you have made a repair, consider whether any calibrations |
| have been affected. |
|
|
Cartridges fail | Remove tape and align cartridges: One frequent cause of |
frequently. | cartridge problems is that the user has forgotten to remove the tape |
| from new cartridges. Remove the tape. |
| Priming cartridges to clear nozzles ' User's Guide. |
| Primer tubes: When you prime cartridges, and there seems to be |
| no result, ensure that the primer tubes are not clogged up with ink. |
| Damaged encoder strip: Another frequent cause of apparent |
| cartridge failure may be a damaged encoder strip. If the small slots |
| on the strip are damaged, the plotter cannot position the carriage |
| correctly during cartridge checking. Try replacing the encoder |
| strip. |
| Faulty cartridge: Some black cartridges (51640A) with USE |
| BEFORE dates of April '96 and earlier may have thin;film damage. |
| This means that the material used for channeling ink behind the |
| nozzles can crack with aging. When this happens, ink seepage may |
| cause many nozzles to fail (eight or more). Replace the black |
| cartridge with one with USE BEFORE date of May '96 or later. |
| Dirty pads: The connection between the carriage PCA and the |
| cartridge flex connector is made by means of a gold bubble on the |
| flex connector that touches a gold pad on the PCA. The Carriage |
| Test includes a test of this connection. When nozzle failures occur, |
| try cleaning the pads with isopropilic alcohol (warnings ' page 6;2). |
| Worn wipers: If the wipers in the service station are worn down, |
| they do not properly wipe the cartridge heads. Easy to replace. |
|
|
Carriage sensor does | Ink on roller: Excessive ink deposits on the drive;roller surface |
not correctly find | can fool the sensor by reflecting the light. (Cleaning roller ' |
media edge. | chapter 4.) |
| Optical sensor incorrectly calibrated: The accuracy calibration |
| includes calibration of the optical sensor on the carriage. You must |
| use polyester film when performing the accuracy calibration. |
| Otherwise the optical sensor will have problems loading some types |
| of media. |
